EXCH

/eks´ch@/ /eksch/ Usage: vt.

EXCH: /eks´ch@/ /eksch/ vt.

To exchange two things, each for the other; to swap places. If you point to two people sitting down and say "Exch!", you are asking them to trade places. EXCH, meaning EXCHange, was originally the name of a PDP-10 instruction that exchanged the contents of a register and a memory location. Many newer hackers are probably thinking instead of the PostScript exchange operator (which is usually written in lowercase).
